A barometer reads 75cm if mercury. When `2.0cm^(3)` of air at atmospheric pressure is introduced into space above the mercury level, the volume of this space cecones `50 cm^(3)`. find the length by which the mercury column desecds.

A barometer reads 75cm if mercury. When 2.0cm^(3) of air at atmospheric pressure is introduced into space above the mercury level, the volume of this space becomes 50 cm^(3) . find the length by which the mercury column descends.

The reading in a barometer changes from 75 cmHg to 25 cmHg when 10 cm^3 of air of atmospheric pressure is introduced in the vaccum space of the barometer tube. What is the volume of air in the tube?

A mercury barometer reads 75cm. Now 3 cm^(3) of atmospheric air is introduced into the tube. The mercury falls to a height of 65 cm and the length of air column above the mercury is found to be 15 cm Calculate the cross-sectional area of the barometer tube.

A barometer tube is 1 m long and 2cm^(2) in cross section. Mercury stands to a height of 75cm in the tube. When a small amount of oxygen is introduced in the space above the mercury level, the level falls by 5cm. Calculate the mass of the oxygen is introduced. Room temperature= 27^(@)C , g=10 m s_(-2) and density if mercury = 13600kg m^(-3) .

A mercury barometer reads 75cm in vertical position . If the tube is inclined by 60^(@) to the vertical, the length of the mercury in the tube will be

If the length of the mercury column in a mercury barometer is 76 cm, what is the equivalent height of the water column ?
